Explanation:

Hello,

Which of the following hypotheses cannot be tested using the scientific method

Arturiano [62]

I believe it's answer #3. Logically, at least.

You can test #1 through trial and error.
You can experiment #2 also through trial and error.
You cannot test #3 through trial and error, because that would be catastrophic.
You can test #4 through a survey and individual study and data collection.
